I'm new to backpacking and just bought my first external frame pack. The pack was used and has some type of mount on the top bar. Here's a pic: https://ibb.co/b2ZbOw What would this mount be used for? I tried Googling this, but came up empty, so any help you can offer will be greatly appreciated.

I was jokingly going to say it is a mount for a helicopter engine, but speaking honestly it doesn't appear to be part of the frame's original equipment, but rather an add-on. Seeing the size of the threaded bolt, it must have mounted something sizeable or heavy.

It is anybody's guess what it was used for, but it is definitely not part of the original pack frame. It shouldn't be too difficult to remove. It appears to be held together with four socket head screws.

I think it's a mount for a gps antenna. to record the actual hiked trail to be superimposed over an Emap.. like the type you see on google for, say the Pacific Crest, which often show two trails one the trail as it appears on published topo's the other the trail as hiked

It looks like it was made by the owner in a machine shop. I have done my share of machining so I know the look. Who knows what it could have been for? Looks like the frame was an old Jansport.
